The collar bush is a core sliding wear-resistant component for the main shaft and eccentric shaft system of crushers, and a precision wearing part. Its primary functions include shaft system positioning, radial support, anti-friction and wear resistance, while absorbing slight vibrations and impacts generated during the operation of the shaft system. It is mainly applicable to cone crushers and gyratory crushers (the gyratory crusher category), and is also used on the main shaft ends of jaw crushers in a small number of cases. It serves as a key basic component that ensures the rotational precision of the crusher's shaft system, reduces wear on transmission parts and improves the operational stability of the equipment.
